Particular embodiments of the subject matter described in this specification can be implemented so as to realize one or more of the following advantages. A lighter modular telecommunications enclosure is installed more easily and more quickly than heavier pre-fabricated telecommunications enclosures. A telecommunications enclosure having a removable door requires less space than a telecommunications enclosure that has a swinging door, thereby enabling the enclosure with the removable door to be installed in more locations than the enclosure with the swinging door.
The details of one or more embodiments of the subject matter described in this specification are set forth in the accompanying drawings and the description below. Other features, aspects, and advantages of the subject matter will become apparent from the description, the drawings, and the claims.
Like reference numbers and designations in the various drawings indicate like elements.
DETAILED DESCRIPTIONA frameless telecommunications enclosure is described in this document. The frameless telecommunications enclosure provides environmental protection for telecommunications equipment (or other electronics) housed in the telecommunications enclosure. In some implementations, the frameless telecommunications enclosure is a modular enclosure that can be assembled by directly connecting panels of the enclosure together, such that the panels, rather than a frame, provide structural support for the enclosure. In some implementations, the panels of the enclosure are fabricated from aluminum, which is lighter than other metals that can be used to fabricate telecommunications enclosures. Additionally, as discussed in more detail below, the enclosure can include a removable door that slidably engages with the enclosure and includes protruding edges that engage seals of the enclosure to prevent water and dust from entering at least a portion of the enclosure. The removable door requires less opening clearance than hinged doors, which enables the frameless enclosure to be installed in locations where there may not be enough clearance for a hinged door to be opened.
The enclosure top 106 is connected to a top end of the side panel 102 and a top end of the side panel 104. The connection between the enclosure top 106 and each of the side panel 102 and side panel 104 can be made independent of a frame. For example, the enclosure top 106 can be directly connected to each of the side panel 102 and side panel 104 by using non-welded fasteners (e.g., screws, bolts, clips, flanges, latches, grommets, pins, snap fasteners, or other fasteners). Ends of the enclosure top that extend between the side panels 102 and 104 are referred to as outer ends of the enclosure top, or as a front outer end of the enclosure top and a back outer end of the enclosure top.
The enclosure top 106 can be a single component or multiple components that together constitute the enclosure top 106. For example, the enclosure top 106 can be a piece of sheet metal (or another material) that is connected to each of the side panel 102 and the side panel 104. In some implementations, the enclosure top includes a heat exchanger that facilitates cooling of the enclosure 100. For example, the enclosure top 106 includes a heat exchanger and heat is removed from the enclosure by way of vents 112 in the enclosure top 106.
The interior panel 108 is also connected to the side panel 102 and the side panel 104. In some implementations, the interior panel 108 is connected to the side panel 102 and the side panel 104 using non-welded fasteners. Ends of the interior panel 108 that extend between the side panels 102 and 104 are referred to as outer ends of the interior panel, or as a front outer end of the interior panel and a back outer end of the interior panel.
In some implementations, the location of the interior panel 108 is based on and/or dictates a size of an equipment chamber that is configured to house telecommunications equipment (or other types of electronic equipment). For example, as illustrated by
Within the equipment chamber is a support panel 114. The support panel 114 has a first end that is connected to the side panel 102, a second end that is connected to the enclosure top 106, a third end that is connected to the side panel 104, and a fourth end that is connected to the interior panel 108. As will be shown and discussed in more detail, the support panel 114 can be positioned centrally in the equipment chamber to support the structure of the enclosure 100 and to mount telecommunications equipment that is installed in the equipment chamber. For example, the support panel 114 has an opening 116 defined therein, through which telecommunications equipment 118 can pass.
The support panel 114 includes mounting holes 120 that can be used to mount the telecommunications equipment 118 to the support panel 114. For example, as illustrated by
In some implementations, the equipment chamber can be sealed to prevent moisture or dirt from entering the equipment chamber. For example, as discussed in more detail below, a sealing material 124, such as a wiper seal strip or another seal, can be attached proximate to (or at) ends of the panels surrounding the equipment chamber. In a particular example, a wiper seal can be attached to (or near) ends of the side panel 102, side panel 104, enclosure top 106, and interior panel so that when a door (discussed below) is secured to the enclosure 100, the wiper seals will be compressed by portions of the door, which will cause the wiper seals to expand and seal the equipment chamber.
In some implementations, the enclosure 100 includes a battery chamber 126 that is surrounded by the side panel 102, the side panel 104, the interior panel 108, and the enclosure bottom 110. The battery chamber 126 is an area in which backup batteries or other equipment that may need to be separated from the telecommunication equipment (e.g., in order to provide proper ventilation) can be stored. As will be discussed in more detail below, the enclosure bottom can include tabs 111a, 111b, and 111c that can be inserted into slots of a removable door to secure the removable door to the enclosure 100.
In some implementations, the back of the enclosure 100 can be configured in a similar manner as the front of the enclosure that is discussed above. For example, the back of the enclosure 100 can also have sealing material 124 attached to outer ends of the side panel 102 and the side panel 104 so that a removable back door of the enclosure will engage the sealing material to seal the equipment chamber.
As illustrated by
In some implementations, the sealing material 124 is attached to each of the side panels by placing the sealing material 124 over a portion of an end of the side panel. For example, as shown in more detail in the expanded view of the boxed area 210, the outer back end 208 of the side panel 104 can include a sealing material mounting edge (“mounting edge”) 212 that is configured to receive the sealing material 124. In this example, the mounting edge 212 is formed at the outer back end 208 by bending the material used to form the outer back end 208 to form a “U” shape. Forming the mounting edge 212 using a “U” shape allows an end of the mounting edge 212 to be even with, or recessed, relative to other portions of the outer back end 208. Additionally, the “U” shape provides a recessed portion 214 of the outer back end 208 that can receive a portion of the sealing material 124. Of course, the sealing material 124 can be attached using adhesives or other materials that can be used to attach the sealing material to the side panels 102 and 104.
The expanded view of the boxed area 210 provides a detailed view of sealing material 124 that is formed into a wiper seal, and how the sealing material 124 can be attached to the mounting edge 212. For example, as shown by the expanded view of the boxed area 210, the sealing material 124 can include a mounting portion 216 that slides over the mounting edge 212. The mounting portion 216 can be, for example, two parallel pieces of the sealing material that, when slid over the mounting edge 212 are spread apart, such that the inward force of the two parallel pieces hold the mounting edge 212 in place.
The sealing material 124, as shown in the expanded boxed area 210, also includes a portion 218. When the sealing material 124 is attached to the mounting edge 212, the portion 218 of the sealing material 124 is located in the recessed portion 214 of the back outer end 208. When the removable door (discussed in detail below) is attached to the enclosure 200, protruding ends of the removable door are also inserted into the recessed portion 214, thereby compressing the portion 218, which seals the equipment chamber.
The description above with reference to the back outer end 208, and the description referencing attaching the sealing material 124 to the back outer end 208, is also applicable to the other ends of the side panels 102 and 104. That is, each of the ends 202, 204, and 206 can also be formed in a manner similar to that discussed with respect to the end 208, and the sealing material can be attached to those ends in a similar manner as that discussed with respect to attaching the sealing material 124 to the back outer end 208.
As illustrated by
In some implementations, the sealing material 124 is attached on a bottom side 312 of the interior panel 108 (e.g., a side of the interior panel that is closer to the bottom end 310 than the other side of the interior panel). For example, the interior panel 108 can have a bended portion 314, which extends from the bottom side 312 toward the bottom end 310. In this example, the bended portion can have a mounting edge similar to that discussed above with respect to
As illustrated by
In some implementations, sealing material 124 can be applied to a bottom side of the enclosure top (e.g., 112 of
The sealing material 124 can be attached to both front and back outer ends of the interior panel 108 (e.g., corresponding to sides on which a front and back door are installed on the enclosure). The sealing material 124 can also be attached to both front and back outer ends of the enclosure top (e.g., e.g., corresponding to sides on which a front and back door are installed on the enclosure).
In some implementations, the protruding ends 404a-404c are formed to engage the sealing material that is attached to both side panels of the enclosure and the sealing material that is attached to the enclosure top. For example, as illustrated by
With reference again to
The sealing member 406 can be attached to the main door portion 402, for example, using non-welded (or welded) fasteners. For example, the sealing member 406 can be attached to the main door portion 402 using a threaded studs 408 (or bolts) and nuts 410 that secure the sealing member 406 to the main door portion 402.
In some implementations, the door 400 can include a rain lip 412 that directs rain away from the enclosure. The rain lip 412 can be, for example, a piece of metal (or another material) having a portion that extends away from the door 400. As installed, the portion of the rain lip 412 that extends away from the door 400 can have a downward slope in the direction away from the door 400. As such, the rain lip 412 will direct water that contacts the rain lip 412 in a direction away from the door 400 (and the enclosure), thereby reducing the likelihood that water will breach the sealing material. The rain lip 412 can be attached to the main door portion 402 in a manner similar to that discussed above with reference to the sealing member 410. For example, the rain lip 412 can be attached to the main door portion 402 using threaded studs 408 (or bolts) and nuts 410 that secure the sealing member 406 to the main door portion 402.
In some implementations, when the door 400 is secured to the enclosure, the rain lip 412 will extend away from the door 400 further than a front edge of the enclosure top 106. For example, with reference to
In some implementations, the rain lip can be formed to create a trough that directs the water to a particular location. For example, the rain lip can be “U” shaped or “V” shaped and angled from one side of the door to the other side of the door so that water can be collected in the “U” or “V” and channeled to one end of the door. Other rain lips can also be used.
In some implementations, the protruding end 404d can have slots 414a, 414b, and 414c defined therein. The slots 414a-414c are formed to receive tabs (e.g., tabs 111a, 111b, and 111c of
An interior panel is connected to each of the first side panel and the second side panel (604). In some implementations, the connection is made independent of an enclosure frame. For example, the interior panel can be directly connected to each of the first side panel and the second side panel. In some implementations, the interior panel has an interior panel outer end that extends between the first side panel and the second side panel. The interior panel can be connected, for example, at a location of the first side panel and the second side panel that is a specified distance from a bottom end of each of the first side panel and the second side panel.
A seal is attached to each of a first outer end of the first side panel, a second outer end of the second side panel, the enclosure top outer end, and the interior panel outer end (606). In some implementations, the seals can be attached at locations discussed with reference to
Protruding ends of a removable door are engaged with the seal that is attached to each of the first outer end, the second outer end, and the enclosure top outer end (608). For example, the removable door can be engaged with the seal in a manner similar to that discussed above with reference to
A sealing member of the removable door is engaged with the seal that is attached to the interior panel outer end (610). For example, the sealing member can be engaged with the seal of the interior panel outer end in a manner similar to that discussed above with respect to
A second side panel of a frameless telecommunications enclosure is formed (704). In some implementations, the second side panel is formed to have a second outer end that includes a second seal. For example, the second side panel can be a side panel similar to side panel 102 or side panel 104 discussed above with reference to
An enclosure top is formed (706). In some implementations, the enclosure top is formed to connect, independent of a frame, to a top end of the first side panel and a top end of the second side panel. The enclosure top can be formed, for example, to have an enclosure top outer end that extends from the first side panel to the second side panel when connected to each of the first side panel and the second side panel. The enclosure top outer end can include a third seal. In some implementations, the enclosure top can be formed to include features similar to those discussed and shown above with reference to
An interior panel is formed (708). In some implementations, the interior panel is formed to connect, independent of a frame, to each of the first side panel and the second side panel at a specified distance from a bottom end of each of the first side panel and the second side panel. The interior panel can be formed, for example, to have an interior panel outer end that extends from the first side panel to the second side panel when connected to each of the first side panel and the second side panel. The interior panel outer end can be formed to include a fourth seal. In some implementations, the interior panel can be formed to include features similar to those discussed and shown above with reference to
A removable door is formed (710). In some implementations, the removable door is formed to include protruding ends that engage each of the first seal, the second seal, and the third seal when the removable door is secured to the frameless telecommunications enclosure. The removable door can be formed, for example, to include a sealing member that engages the fourth seal when the removable door is secured to the frameless telecommunications enclosure. The removable door can be formed to include features similar to that discussed and shown above with reference to
